IMPROVEMENT IN THRASHERS AND SEPARATORS.

- Specification forming part of Letters Patent No. 221,463, datedNovember 11, 1879; application filed June 26, 1879.

To all whom it may concern:

Be it known that I, PETER HORN, of Hagerstown, in the county ofWashington and State of Maryland, have invented certain new and usefulImprovements in Thrashing-Machines and Grain Separators; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same,reference being had to theaccompanying drawings and to letters of reference marked thereon, whichform a part of this specification.

In the accompanying drawings, Figure l is a top view of myimprovedthrasher and separator. Fig. 2 is a side view of the same. Fig. 3 is alongitudinal vertical section. Figs. 4, 5, and 6 are detail views.

Upon the frame A are mounted the thrashin g-cylinder B, the fork orstraw-shaker O, and straw-carrier D, in the rear of which is the stackerE.

The fan F is placed directly underthe thrashing-cylinder, and the sievesG and H are under the fork or shaker, thus making the machine verycompact.

The grain is fed into the hopper I and thrashed by cylinder B in theusual way, when the straw passes upon the fork O, which is shaken bymeans of the cam Jon the shaft of the flanged cam-wheel K, which willhere inafter be more fully described. This fork has two sets of tines orteeth, 00, in order to divide and thoroughly separate the straw, andthus expose the same to the blast, and facilitate the escape of thegrain.

The front teeth are short, and they divide the bundles and scatter thestraw loosely upon the longer back teeth.

Both the fork and the sieves G and H have a lateral motion, being shakenby the elbowshaft N, which is rocked to and fro by means of thecrank-pin O and connecting-rod P, Fig. 2. The sieves are shaken by meansof the flanged wheel K, the rim of which runs between twofriction-rollers, R, on the arm S, extended from the sieveframe. Theflanged wheel also shakes the straw-carrier D, the rim of the wheelbeing bent to form a cam, and runningin a grooved pulley, T, on theshaft of the lower rollers, over which the straw-carrier runs. By thisarrangement the inner or receivin g end of the straw-carrier is shakensidewise, while the band U gives it motion on the rollers.

The front shoe, V, has a down-set, W, and an adjustable wind-gate, X, toregulate the blast and direct the same more orless upon the clown-setdirectly under the axis of the fork. Another adjustable wind-gate, Y, isplaced in the passage between the down-set and the back shoe, Z. Thesewind-gates are held at any desired angle by means of a hasp, a, whichhooks into one of the notches on the plate b, Fig. 1.

The stacker E is attached to the frame by means of S-shaped swingingbraces cl, so as to be folded over upon the top of the frame fortransportation. This brace is pivoted at both ends, as seen in Fig. 5,and, by their peculiar shape, act as supports for the stacker whenunfolded, as shown in Fig. 1.

On the mouth of the discharge-spout is attached aself-lockin gbag-holder having a rocking elbow-shaft, e, to which is hinged a lever,f, for holding the bag and for raising and holding the slide 9. When theelbow-shaft c is raised the lever f is employed to raise the slide andlock the same. The mouth of the bag is hung upon the wide end of thisleverf, which thus holds both the bag and the slide; and when the bag isfilled the lever and elbowshaft are tilted, and drop with the slide, asseen in Fig. 4.. The fan is provided with an adjustable slide, 9, toregulate the blast.

Having described my invention, what I claim is- 1. The combination, withthe thrashing mechanism, of a shaking-fork, (3, arranged in rearthereof, and provided with short teeth, 0, and long teeth, 0, arrangedon differentplanes, substantially as and for the purpose herein shownand described.

2. In athrashing-machine, the combination, with an endless revolvingstraw-carrier, D, of the grooved pulley T, and revolving cam K, wherebysaid carrier is adapted to receive a laterally-vibratin g movement,substantially as specified.

3. The combination, with the fork O, of the revolving cam J, crank-pinO, elbow-shaft N, connecting-rod P, and revolving wheel K, for
